• 7:05 p.m. ET: The Big Series will be in Baltimore, where the Orioles face the Rangers and attempt to stop their drift away from the playoff pack. Baltimore, one of the best early-season stories, is now 3½ games behind the Red Sox in the AL East and 2½ behind Oakland and Minnesota in the wild-card race. Joaquin Benoit takes the mound for Texas, while Daniel Cabrera throws for Baltimore.
• 7:15: The Devil Rays beat on the Yankees earlier this season, and then over the weekend they took a big bite out of the Orioles. Now they face the Red Sox, with Doug Waechter throwing against Boston's David Wells. The Most Likely Guy To Go Deep is David Ortiz, who has two homers in seven at-bats against Waechter in his career.
• 8:05: At home, the Phillies have been tough, playing .600 ball. On the road, they've had trouble -- and tonight, they go to Houston to play the red-hot Astros. Andy Pettitte, who has allowed one earned run or less in his last six starts, throws for Houston.
• 9:05: The Must-Watch Game of the Night will be in Colorado, where the Mets begin a week of play that could sway their future, immediate and long-term. If they take the series against the Rockies -- and that's not always easy -- then the pressure will mount on general manager Omar Minaya to add help before the trade deadline. If they get beat up by the Rockies, on the other hand, then they might maintain their current course of inaction and simply wait for the season to play out. Tom Glavine, who has pitched better of late, starts for the Mets, in search of career victory No. 270, against Jose Acevedo.
• 10:05: The Best Pitching Matchup of the Night will be in Oakland, where a couple left-handers go at it: Barry Zito of the A's against C.C. Sabathia of the Indians. Zito has won six of his last seven decisions and lowered his ERA from 5.84 on May 1 to his current 3.55.
